METHOD AND AIIFPAKATUS F03 rmorno'ronnsr A ncaaen filed February 20,1925". SiiaiiH/ibflii.

This invention relates to a method and whereby, they can be securelyheld in place" in all kindsof soil and under all sorts of conditions. I

A still further object concerns the proV1-' sioi of a simple andefficient method and a-p paratuswhereby' an old pole in use can beeither repaired in place with no disturbance whatsoever in the wires orinterruption in the service, or an old pole can be removed A the r'epalrof a eworn-oiit,pole which has beand a new one substituted. Anotherobject concerns tlie'provision of simple and efiicient m'eans wherebyold or "new polescan be eflijcliently sup orted from an anchor or basein the gro'iin and yet be" held off the ground to eliminate thed'eleterious effects of moisture on'th'e poles'when they are embedded in theground.

Theinvention is illustrated in the" draw ingsl, ofw hich Figures 1,stages in the operation of repairing a worn outj'pole withoutdisturbingthe wires;

The form of the invention shown in the drawings is' a preferredft'or'ni,although it the provision of 2 and 3 illustrate successive is a sectionon the line 6-6 of is understood that modifications the constructioiiand arrangement of the partsjand 1n the character of, the inatei'ialsused: may

ts general aspect the invention includesjthe idea of providing aconcrete base of the'invention as set forth in the appended embeddedinthe ground atthe location de sired'for a'pole and supporting a socketin said base with a: portion of the sofc'ket extending} above the basepiaiijchorage and adaptedto' receive'thepo'le, said pole being supportedin thevsocket' slightly above the top of the basevsojthat'there will bean air space between the bott'ol'nfof the pole and the top of theanchorage, In thisrnaniiei' the pole isfir'mly held irii'po's'ition andat the sajiii'e t-inieig-t'o a Inini'm'u'in' extent,subjectecltothedeleterious action of moisture." v

- further aspect of the inveiitioninvolves hole; emhedding therein theiron bars, with reenforcing elements, After the concrete has hardened;the platform (studding such a323, 12) is removed, "as W6 as the. bars16; the concrete to'p'tliat emerges from the ground is finished smoothand. sloped from the cente r to the sides to prevent the accumulation ofWater on it. The irons or steel pieces and bolts and the lower part ofthe polehave a coat of tar or paint to prevent rusting. 4 M p o o Atiirther aspect of the invention involves the modified forms of socketsof different kinds of poles, and also modified forms of anchorages toadapt the method and ripen-a tus for'use in difleren't kinds ofso'ilandconditions of soil. a g

The preferred form of the, invention, showing the method, is .set forthin Figs. 1, 2 and In thesev figures a pole is shown which has becomeeaten away by the conditions of the soil and the elements and must berepaired. The pole is sawn off along the line 11, slightly above theground, and the bottom of it is moved laterally on the platform 12. Thestump 13 of the pole in the ground is then lifted out of the ground byany suitable means, such as a eham 1i and a jack apparatus 15, shown inFig. The pole is, in the meantime, held in position by means of the bars16, which are manually adjustable.

After the stump has been removed, a concrete anchorage 17 is formed inthe hole, and in this anchorage socket elements 18 are placed with theirupper ends extending above the ground. These socket elements may be ofany suitable type, as hereinafter to be described more in detail. Beforethe anchorage has been formed the pole is moved into engagement withinthe socket elements and fastened thereto by any suitable means, such asbolts 19. It will be observed that there is an air space 20 between thebottom of the pole and the top of the anchorage. This is for the purposeof preventing the pole from coming directly in contact with moisturefrom the soil and being subject to other deleterious influences therein.In this way a pole can be readily repaired while the wires 21 areundisturbed. It will easily be perceived that after the pole has beensawn off, the stump removed and an anchorage formed, that a new pole canbe put in the socket and that itwould not be a dillicult matter to shiftthe wires from the top of the old pole to the top of the new one withoutmaterially disturbing them, after which the old pole can be lowered.This would permit a new pole to be substituted for the old one withoutmaterially disturbing the wires.

Figs. 4, 5 and 6 illustrate more in detail the character of theanchorage and the socket. The concrete anchorage 17 is shown, and thesocket elements are, in the form shown, made of U bars 22 spaced atsuitable distances apart to form an opening of the shape of the pole. Inthe case shown in Figs. l. 5 and (3, the pole is square. therefore thesocket elements are so placed that the space forms a squaretherebetween. This construction is adapted for either square or roundpoles. The upper ends of the socket elements extend above the concretebase and are provided with bolts 19. or similar elements, which extendinto the pole to hold it in place. In order to permit the pole to beremoved from the socket, one of the socket elements is made in sections24: and 25 and the sections are detachably connected together by aclamping plate fastened to the sections over the joint. When thisclamping plate is removed, the upper section 25 can then be removed ,andby moving the bolts 19 which secure it and the other clamping members tothe pole the pole slid out of the socket. This construction alsofacilitates the placing of the pole in the socket.

In the modification shown in Fig. 7, the socket elements 22 are U bars,but instead of being fastened to the pole by bolts they are embraced bya strap such as 27 provided with adjusting bolts 28 to tighten and clampthe socket elements around the pole without the use of bolts.

In order to adapt the anchorage to different kinds of soil, I providedifferent shapes of anchorage, as shown in Figs. 8 to 13, inclusive. InFigs. 8 and 11 I show an anchorage 29 of a frusto conical shape adaptedfor swampy land. In this case the lower ends of the socket elements arenaturally curved or deflected to extend down into the corners of thebase or anchorage. In Figs. 9 and 12 I show a similar frustoconicalanchorage 30 being gradually sloped and beveled to adapt it for sandysoil. In Fig. 10 I show an anchorage 31 having a jagged outer surface to)ermit it to firmly hold the pole on a hilly dirt slope. In Fig.

.3 I show an anchorage 32 which has a slot formed therein to permitpassage therethrough of conduits or cables 33 which are not disturbedduring the formation of the anchorage.

In the form shown in Figs. 9 and 12 the anchorage bars are preferably inthe form of wings 31, preferably at right angles to each other.

hat I claim is 1. The combination with a pole, of a concrete base forthe pole, a plurality of channel bars having their lower ends embeddedin the base, and their upper ends projecting from the base and securedto the pole, one of the upper end portions of said bars being in twosections, and means for securing the sections together above the ground,said means consisting of a plate in the channel of the sections andscrews or bolts passing throughthe plate and sections into the pole.

2. The methodof repairing poles, which comprises severing the pole abovethe surface of the ground, ren'ioving the stump of the pole from theground, disposing a. plurality of members in the hole left by theremoval of the stump of the pole with portions thereof projecting abovethe ground, placing the severed end of the pole between the projectingportions of said members. fastening the projecting portions of saidmembers to the pole, and then pouring concrete in said hole around themembers to form a supporting base with the lower portions of saidmen'ibers embedded therein.

3. The method of repairing poles, which comprises severing the poleabove the surface of the ground and at a point where the sound woodbegins, removing the stump of the pole from the ground, disposing a.plurality of members in the hole left by the removal of the stump of thepole with porsupporting base with the lower ends of the ions thereofprojecting above the ground, members embedded therein, and spacing theplacing the severed end of the pole between lower end of the pole abovesaid base to pro- 10 the projecting portions of said members, fas- Videan air space between the severed pole 5 tening the projecting portionsof said memend and said base.

hers to the pole, then pouring concrete into said hole around saidmembers to form a ALBERT EHRLER.
